Technical Summary This document describes FFV1, a lossless video encoding format. The design of FFV1 considers the storage of image characteristics, data fixity, and the optimized use of encoding time and storage requirements. FFV1 is designed to support a wide range of lossless video applications such as long-term audiovisual preservation, scientific imaging, screen recording, and other video encoding scenarios that seek to avoid the generational loss of lossy video encodings. This document defines version 0, 1 and 3 of FFV1. Working Group Summary Since FFV1 (version 0,1,3) already exists and is in production use for many years already, there was a clear consensus for these versions. Although the number of people interested in, and working with this format is growing, the document itself was written and reviewed by a rather small group. There do not appear to be any concerns in terms of process or consensus. Document Quality This small group consists of a team of experts in audiovisual format encodings, where most of them have actively been working with FFV1 since its early days. The knowhow and expertise in this group is a good mix between AV, codec implementation, real world lossless video use cases, as well as mathematics. The team itself and the document shepherd finds the document to be of good quality, but two successive responsible Area Directors raised numerous issues about document quality and layout about earlier versions. The authors have been slow but steady in responding. Personnel The document shepherd is Peter Bubestinger-Steindl. Murray Kucherawy is the responsible Area Director, and provided an expert review on the IANA media type registration.
